# Typography: Font Theming

**Title Font**

Controls the typeface and scale for all **H1, H2, and H3 headings** across the page: Hero titles, section headings, card headings, FAQ questions, and any component using a heading element.

Family
The font applied to all headings. Choose from 1,945+ Google Fonts or any custom font you've added below. **Display and serif fonts** (Playfair Display, Bebas Neue, Cormorant) work well for headings; save the readable sans-serifs for body text.

Weight
The font weight for all headings globally. **700 (Bold)** is the default. Go higher (800, 900) for impact-heavy conference branding; go lower (300, 400) for editorial or luxury event aesthetics, but verify the font supports those weights.

H1 Size
Size of H1 elements in `em`. Used in **Hero titles, Event Title, and top-level page headings**. Default `2.5em`. Increase for bold above-the-fold impact; reduce if your event name is long and wraps awkwardly on mobile.

H2 Size
Size of H2 elements. Used in **section headings and major content headings**. Default `2em`. Should be noticeably smaller than H1 to maintain clear visual hierarchy.

H3 Size
Size of H3 elements. Used in **card headings, FAQ question labels, speaker names, and sub-section titles**. Default `1.5em`.

**Paragraph Font**

Controls the typeface and scale for all **body text**: paragraphs, button labels, form fields, navigation items, card descriptions, list text, and any non-heading copy.

Family
The font for all body text. Prioritize **readability at small sizes**: Inter, Poppins, DM Sans, and Nunito are popular choices. Avoid display or decorative fonts here; they hurt legibility in long paragraphs and form fields.

Weight
Font weight for body text globally. **400 (Regular)** is standard. Use **500 (Medium)** if your base font feels too thin on certain backgrounds.

Large
Size for large body text: **lead paragraphs, feature descriptions, Hero subtitles**. Default `1.15em`.

Body
The base size for **standard paragraphs, card descriptions, and all general copy**. Default `1em`. Increase to `1.05em`–`1.1em` to improve readability for older audiences.

Caption
Smallest text size for **image captions, timestamps, metadata, and fine print**. Default `0.875em`. Don't go below `0.75em`: anything smaller fails WCAG readability guidelines.
